Distributed Event-Triggered Current Sharing Consensus-Based Adaptive Droop Control of DC Microgrid

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

Overall, the article is well-written and effectively presents the premises promised by the proposed methodology at this paper introduction. However, some details need to be adjusted before its acceptance and publication:

Review and correct formatting errors in the document, such as unlinked references and equations embedded in the text that are not properly displayed (too small font).

Figure 4 is missing from the document. This issue should be resolved.

The term “communication cost” is used in the document. While its intended meaning is clear from the context, it is not the most appropriate term, as it initially suggests a study on the implementation cost of the proposed methodology. This should be checked, considering more suitable terms such as “communication pressure,” which is also used in the document and aligns better with the explanation provided.

For the case study, it is important to include a general schematic of the circuit. Then, the parameters described in the tables and text can be supported graphically, making it easier for the reader to understand.

Include a brief discussion on the challenges of implementing the proposed methodology in a system with “traditional droop control”.

The paper cite few previous papers from the journal to which the article is being submitted (Electronics). It is advisable to review and include relevant references from this journal to establish an editorial stronger connection with the topic discussed.

The paper proposes an adaptive droop control strategy for DC microgrids based on distributed event-triggered current-sharing consensus and multi-agent consensus algorithms. The strategy aims to address the challenges of traditional droop control in achieving precise current distribution, bus voltage regulation, and communication costs. The research idea has the potential to improve the performance and efficiency of DC microgrids. Major revision should be considered to improve the quality of the research.

1. The mathematical models and equations are clearly defined and correctly derived. The use of Lyapunov stability theory to prove the stability of the proposed control strategy is rigorous. However, some details on the parameter tuning and design of the control laws could be further elaborated to improve reproducibility.
2. The simulation results effectively demonstrate the performance of the proposed control strategy under load step changes and converter faults. The current distribution error and communication cost reduction are significant. More detailed comparisons with other existing control strategies are suggested to strengthen the validation of the proposed method.
3. The conclusions summarize the main contributions of the paper clearly. It is suggested to discuss any limitations of the proposed control strategy, such as its performance under more complex network topologies or communication delays.
4. The paper could benefit from a more concise introduction that clearly outlines the research problem, objectives, and contributions. It is suggested that the introduction should include a clearer statement of the research problem, the research gap in the existing literature that the paper aims to address, and the main contributions.
5. The literature review could be expanded to cover more recent works on event-triggered control and consensus algorithms in DC microgrids. It is suggested to include more recent works on event-triggered control and consensus algorithms in DC microgrids to situate the proposed method within the current research landscape, e.g., S. Huang et al., "Robust Distributed Fixed-Time Fault-Tolerant Control for Shipboard Microgrids With Actuator Fault," in IEEE Transactions on Transportation Electrification, doi: 10.1109/TTE.2024.3411289.

Comments and Suggestions for Authors

The abstract contains too many technical terms without initial context. Consider simplifying or briefly defining key terms for a broader audience.
The introduction could benefit from a smoother transition between the problem statement and the proposed solution.
 Some figure captions lack descriptive detail. Adding more context would help readers understand their relevance.
 Terms such as "droop control" and "hierarchical control" should be consistently defined and used throughout the paper.
Some sentences are lengthy and complex. Consider breaking them down for better readability.
The conclusion could summarize key findings more explicitly and suggest practical applications of the proposed method
